BUCKET CONVEYER.

Specification of Letters Patent.

Patented Nov. 17, 1914.

Application filed May 12, 1914. Serial No. 838,010.

To all 20/1 am it may concern Be it known that I, HANS ZUBLIN, a citizenof Switzerland, residing at Buenos Aires, Argentina, have inventedcertain new and useful Improvements in Bucket Conveyers; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

The object of this invention is to provide improved means whereby aseries of buckets, carried by a cable and traveling through pipes, istaken around a bend or elbow at a variable angle.

The invention is illustrated in the accom panying drawing, in which-Figure 1 is a side view, partly in section, Figs. 2, 3 and 4 beingsections on the lines AB, CD and EF respectively.

The buckets or scrapers a are fixed in series to a rope I), which atthat part of the conveyer which is shown in the drawing travels throughtwo pipe sections 0, d, hinged to each other at c by a joint f, so thatthey can be rocked as indicated by the arrows :0, to alter the angle atwhich the two sections are set, or to place them in a straight line. Onthe pivot e is mounted a grooved guide wheel 9, for which r sprocketwheel may be substituted if a chain is used instead of the rope I).

In order that the wheel need not be of inconveniently large diameter,even if the conveyer is working at high speed. the wheel has around itscircumference a rib or flange 2'. on which the rope orchain rests, thebuckets a having slots Z enabling them to pass the said rib, as shown inFigs. 2 and 3.

The wheel 9 has curved side flanges b, so that its circumference formsan annular trough with the rib i at the center, and the buckets a arepartly sunk in this trough while traveling on the wheel. In crosssection the trough conforms to the adjacent parts of the pipes c and (Z,which enter the trough approximately tangentially with the base thereof,the rims of the pipe mouths abutting against the wheel at p, 7). Thetrough thus forms a channel connecting the two pipes. The buckets areguided in the pipes so that their slots Z run cleanly 'on to the rib 2',and off same, without jarring. For

this purpose there is in each pipe a rib m, alined with the rib 2' andof the same height. or of a somewhat less height. I

The guide wheels or rollers at the ends of the conveyer, or where loadis taken up and discharged, must of course also have ribs which enterthe slots Z, but they need not have the channeled or trough like shapeshown in Fig. 2. The bend or elbow of the conveyer shown in Fig. 1 isprotected by a collapsible or foldable guard 97,, to prevent any part ofthe load from being thrown out by centrifugal force at this part. Thetwo pipes c and (Z are provided with curved overlapping tongues 0extending around part of the circumference of the wheel, and forming aguard inside the elbow or bend.

l/Vhat I claim as my invention and desire to secure by Letters Patent ofthe United States is:

1. In a bucket convcyer the combination of two pipes, a hinge jointconnecting said pipes end to end, a wheel concentric with the axis ofsaid joint, a cable in said pipes traveling on said wheel, and bucketsfixed to said cable, havin slots enabling them to travel with saidczIfle around said wheel.

2. In a bucket conveyor the combination of two pipes, a hinge jointconnecting said pipes end to end, a wheel concentric with the axis ofsaid joint, having a rib formed on its circumference, a cable in saidpipes traveling on said rib, and buckets fixed to said cable, havingslots enabling them to travel with said cable around said wheel.

3. In a bucket conveyer the combination of two pipes, a hinge jointconnecting said pipes end to end, a wheel concentric with the axis ofsaid joint, having a channel formed in its periphery. a rib formed insaid channel around said wheel, acable in said pipes traveling on saidrib, and buckets fixed to said cable having slots enabling travel withsaid cable around said Wheel, and ribs in said pipes, engaged with saidslotted buckets, guiding the latter to the rib on said wheel.

In testimony whereof I hereunto affix my signature in the presence oftwo Witnesses.

HAN S ZUBLIN.
